Age-Related Histological Changes in Kidneys of Brown Norway Rat
In this study, age-dependent histological changes in the kidneys of Brown Norway rat, a strain useful for conducting aging research, were evaluated. Examination was performed at 3, 12, 18, 24 and 30 months of age. Sclerotic and hypertrophic changes of the glomeruli were observed, and quantitative scores of these changes persistently increased with age. A marginal increase in scores was observed...
متن کاملAge-related changes in the expression of 11beta-hydroxysteroid dehydrogenase type 2 in rat Leydig cells.
Previous studies in rats have shown that the ability of Leydig cells (LCs) to produce testosterone significantly declines with age. To address the possible mechanisms by which aging LCs lose their steroidogenic function, we determined the effect of aging on the expression of 11beta-hydroxysteroid dehydrogenase (11beta-HSD) type 2. The enzyme plays a protective role in blunting the suppressive e...
متن کاملGene expression in the aging brown Norway rat epididymis.
The mammalian epididymis is the site where spermatozoa are matured and then stored. Though many studies have described epididymal functions and their regulation, little is known about how aging affects this tissue. The Brown Norway rat, which does not show the many age-related pathologies common to other rat strains, was used as a model to study aging of the epididymis. The present study was de...
متن کاملAging and the brown Norway rat leydig cell antioxidant defense system.
Previous studies have shown that testosterone production by the Leydig cells of aged Brown Norway rats is reduced from the relatively high levels produced by Leydig cells of young rats and that this reduction is not secondary to decreased serum luteinizing hormone concentration. The free radical theory of aging proposes that imbalance between pro-oxidants and the antioxidant defense system ulti...
متن کاملAge-related gene expression in Tourette syndrome.
Because infection and immune responses have been implicated in the pathogenesis of Tourette syndrome (TS), we hypothesized that children with TS would have altered gene expression in blood compared to controls. In addition, because TS symptoms in childhood vary with age, we tested whether gene expression changes that occur with age in TS differ from normal control children. Whole blood was obta...
